The Austrian World Summit, founded by Schwarzenegger in 2017, has emerged as a significant platform for discussions surrounding climate action. Schwarzenegger, at 78, has become a prominent figure in the fight against climate change. The summit gathers a diverse array of participants, including political leaders, scientists, and business executives, all aiming to explore pragmatic solutions to urgent environmental challenges.

During a segment on the Morning Joe programme, Schwarzenegger stressed the necessity to combat pollution, referencing his iconic role in the “Terminator” series. He remarked, “The theme of the conference is that we are unstoppable,” highlighting advancements in environmental policies from various states across the United States, including California, Texas, and Massachusetts.
The summit also attracted a range of influential figures, such as former U.S. Vice President Kamala Harris, Austrian President Alexander Van der Bellen, and Chancellor Christian Stocker. Their presence underscored the importance of international cooperation in addressing climate issues.
While Schwarzenegger frequently participates in public engagements, joint appearances with Milligan are relatively infrequent. The couple first crossed paths in 2012 when Schwarzenegger required rehabilitation for a shoulder injury before filming “Escape Plan,” alongside Sylvester Stallone. Stallone recommended Milligan, a qualified physical therapist, to assist with his recovery process.
Reflecting on their initial meeting, Schwarzenegger previously shared with PEOPLE that once his therapy concluded and filming was completed, he felt compelled to express his gratitude to Milligan. “I called her back and took her out for lunch to say thank you,” he explained. This initial connection gradually blossomed into a romantic relationship.
In subsequent years, the pair have chosen to maintain a level of privacy regarding their relationship, occasionally making public appearances at film premieres and charity events. Despite this discretion, Schwarzenegger has expressed deep admiration for Milligan. In an interview in September 2023, he said, “We have so many things in common. I think the world of her. I love that she’s into working. She’s clearly independent. She just is driven as hell.”
Milligan, now 51, has been an integral part of Schwarzenegger’s journey, contributing to his health and well-being over the years. Her professional background as a physical therapist has been pivotal, particularly during his recovery phases.
The couple’s bond continues to thrive as they navigate their careers and shared interests. Their involvement in the Austrian World Summit illustrates their shared commitment to significant global issues, particularly environmental sustainability.
As the world increasingly turns its focus on climate change, Schwarzenegger’s initiatives and Milligan’s support reflect a personal dedication to fostering meaningful change. The duo exemplifies the intersection of celebrity influence and environmental advocacy, aiming to inspire others to engage in the fight against climate degradation.
